HOWARD R. SARGENT, OF SCHENECTADY, NEW YORK, ASSIGNOR TO GENERAL ELEC- TRIO COMPANY, A CORPORATION OF NEW YORK.

INGLOSED FUSE.

Application filed August 22, 1913.

To all whom it may concern:

Be it known that I, IiIowAuD R. SARGENT, a citizen of the United States, residing at Schenectady, county of Schenectady, State of New York, have invented certain new and useful Improvements in Inclosed Fuses, of which the following is a specification.

My invention has reference to an inclosed fuse of the reloadable type, and has for its object an improvement in a device of this character.

For a fuller understanding of my invention reference may be had to the accompanying drawings, in which- Figure 1 a longitudinal sectional view of an inclosed fuse of the blade type embodying the preferred form of my invention; Fig. 2 is a perspective view of the same form showing the parts disassembled; Fig. 3 is a longitudinal section of an inclosed fuse of the ferrule type in which a modified form of my invention is embodied; Fig. i is a crosssection on the line 3 3, Fig. 3; Fig. 5 is a longitudinal section of an inclosed fuse also of the ferrule type showing another modified form of my invention, and Fig. 6 is a section on the line 5-5, Fig. 5.

Referring to the drawings, and first to Figs. 1 and 9., 1 is an insulating tube for housing the fuse, and 2 is the metallic cap or ferrule therefor provided with an end slot 3 through which the supporting blade 4 for the fuse passes. The cap is secured to the end of the shell 1 by screws 5. A fuse supporting disk 6 having substantially the same diameter as the internal diameter of the cap 2 is secured in position between the end of the shell 1 and the inner end face of the cap. The disk 6 is provided with a radial slot 7 xtending from the central part of the disk to the peri 'ihe'ry. Within this slot is received a contracted portion 8 of the blade 4:, which is formed by transverse grooves or notches 9 in the blade 4. The inner end of the blade is provided with a screw 10, by which one end of the fuse is secured to the supporting blade 4.. The device shown in Figs. 1 and 2 is assembled by placing the contracted portion 8 of the blade 4 in the slot of the disk The disk is then placed against the end of the shell and the cap passed over the blade 4 and secured to the shell.

In the form. of my invention shown in Specification of Letters Iatent.

Patented July 25, 1916.

Serial No. 786,070.

Figs. 8 and 4 the disk 6 is provided with a central transverse slot 11 through which the inner end of the fuse 12 passes. The fuse is bent at 90 degrees and is secured in position between the cap and the disk and passes over the edge of the disk between the flange of the cap and the end of the shell and may be conveniently secured in position by one of the screws 5.

In the form of my invention shown in Figs. 5 and G, the disk 6 is provided with an annular flange 13, the flanged portion being secured in position between the cap 2 and the end of the shell 1. The disk is, in this form, provided with a slot 11, as in Figs. 8 and 4-, through which the fuse 12 passes, the inner end of the fuse in this case being secured to the outer face of the disk 6 by a screw 14;.

It will be apparent that my invention provides an inclosed fuse which is simple in construction and is readily assembled by any person who is not skilled in the art.

What I claim as new and desire to secure by Letters Patent 0f the United States, is

1. In an inclosed fuse, a tubular insulat ing shell, a disk at one end of said shell having a slot extending inward from its periphery, a supporting blade having a contracted portion engaged in said slot in the disk so that said blade and said disk cannot move lengthwise with reference to one another, and a metallic cap having an end slot for said blade secured on the end of the shell with said disk within it, said blade and disk being separable from one another by movement of said blade outward in said slot.

2. In an inclosed fuse, a tubular insulating shell, a disk at one end of said shell having a radially extending slot, a supporting blade having a contracted portion engaged in said slot so that said blade and said disk cannot turn or move lengthwise with reference to one another, and a metallic cap having an end slot for said blade secured on the end of the shell with the disk within it, said blade and disk being separable fromone another by movement of said blade outward in said slot.

3. In an inclosed fuse, a tubular insulating shell, a metallic cap with an end slot secured on the end of said shell, a disk abutting against the end of said shell within said cap and having a slot extending inward from its periphery, and a supporting blade rable from one another by movement of said extending through the aforesaid slot in said blade out-Ward in said slot. 10 cap and having an angular contracted por- In Witness whereof, I have hereunto set tion so engaged in said slot in said disk that my hand this 20th day of August, 1913.
